Device features and design elements for long-term adhesion
An electronic device for long-term adhesion to a mammal includes a housing with an electronic component. The electronic device may include a first wing and a second wing, each being integrally formed with the housing. An electrode is positioned on a bottom surface of each of the wings, the electrodes electrically connected to the electronic component. An adhesive layer is provided for adhesion to a surface of the mammal. The adhesive layer may cover a portion of the bottom surfaces of the wings but generally does not cover the electrode or a bottom surface of the housing. A method of applying an electronic device to a mammal includes removing first and second adhesive covers from first and second wings of the electronic device to expose an electrode and an adhesive coated on a bottom surface of each wing.
1. An electronic device for long-term adhesion to a user, the device comprising:
a housing comprising a physiologic data collection circuit, the housing positioned over a flexible layer extending from the housing, the flexible layer comprising an electrode positioned on the bottom of the flexible layer at a position distal from the housing, wherein the flexible layer comprises a polymer upper layer overlying an electrical connection, the electrical connection extending from the physiologic data collection circuit to the electrode, the polymer upper layer adhered to a polymer lower layer underlying the electrical connection;
a lower adhesive layer positioned on the flexible layer and configured to adhere the electronic device to a user, the lower adhesive layer extending at least partially below the housing; and
wherein the housing is configured to tilt at an angle relative to the lower adhesive layer in response to movement of the user.
2. The electronic device of claim 1 , further comprising a flap extending beneath the housing.
3. The electronic device of claim 1 , wherein the housing is rigid.
4. The electronic device of claim 1 , wherein the housing is configured to remain connected to the flexible layer when the housing is tilted at an angle relative the lower adhesive layer in response to movement of the user.
5. The electronic device of claim 1 , further comprising a hinge portion adjacent the housing.
6. The electronic device of claim 1 , wherein the lower adhesive layer comprises a hydrocolloid adhesive.
7. The electronic device of claim 1 , further comprising a synthetic material layer positioned above the lower adhesive layer.
8. The electronic device of claim 1 , wherein the physiologic data collection circuit is configured to collect cardiac rhythm data from the user.
9. The electronic device of claim 1 , wherein the polymer upper layer extends horizontally away from the housing beyond a boundary of the electrode.
10. The electronic device of claim 9 , further comprising an upper adhesive layer positioned over the polymer upper layer.
11. The electronic device of claim 10 , wherein the upper adhesive layer is positioned above the electrode.
12. The electronic device of claim 11 , wherein the upper adhesive layer extends horizontally away from the housing beyond a boundary of the polymer upper layer.
